I don't know if this is featured, but arrived on the higher platform (2nd black "octopuss") the screen becomes all white with some yellow circle.The game isn't frozen, as I can still hear the jumping sound. The view is just opaqued. From here, I can't pursue the game.

So a missing image/texture (on the server) around here. Check in your project what you try to display when we are close to this ladder and that is missing on dropbox.Maybe your chrome stored the texture in cache, but it wasn't uploaded/exported to the hosted project.

Couldn't even get past a white screen when trying to run on Firefox 4.0 once it indicated the game was loaded. I then updated to 8.0 and as soon as I got up the stack of crates and made it about 1/3 the way across the platform with the second black germ, I too got the same screen discussed above.
